AC Back Surface Recombination Velocity in n<sup>+</sup>-p-p<sup>+</sup> Silicon Solar Cell under Monochromatic Light and Temperature

Abstract: Excess minority carrier's diffusion equation in the base of monofaciale silicon solar cell under frequency modulation of monochromatic illumination is resolved. Using conditions at the base limits involving recombination velocities Sf and Sb, respectively at the junction (n + /p) and back surface (p + /p), the AC expression of the excess minority carriers' density δ (T, ω) is determined. The AC density of photocurrent J ph (T, ω) is represented versus recombination velocity at the junction for different values… Show more

“…At high speeds (Sf) of the recombination of minority charge carriers at the junction (short-circuit condition of the solar cell), the photocurrent density is constant. This constant value corresponds to the density of the shortcircuit current, and this makes it possible to establish the following equation [19,21,28,30,31]: .…”

“…Aux grandes vitesses (Sf) de la recombinaison des porteurs minoritaires de charge à la jonction (condition de court-circuit de la photopile), la densité de photocourant est constante. Cette valeur constante correspond à la densité du courant de court-circuit, et ceci permet d'établir l'équation [19,21,28,30,31] suivante: . tanh ( 𝐻 𝐿(𝜔,𝑁 𝑏 ) )…”
